What is Newton's Law of Viscosity?
What are examples of Newtonian Fluids and Non Newtonian Fluids?
What is the difference between Kinematic Viscosity and Viscosity?
What is used to measure density in the Laboratory?
Tell us Renette...
Viscosity is equal to the ratio of the shear stress to the rate of shear strain.
Or simply as the "thickness" of a fluid.
Newton's law of viscosity states that the coefficient of viscosity is equal to the ratio of the shear stress to the rate of shear strain.

A Newtonian fluid is a fluid that possesses a constant, or near constant, viscosity regardless of the shear rate applied.
Non-Newtonian fluids do exhibit a change in viscosity as shear rate changes.
